I started working on a pizza trailer concept a year or so ago and the project is now gaining steam. I don't have the ambition of John to run a serious operation, i just like to build things and make pizza. I have some friends who i'll loan this to if it works and i'm sure we'll do some parties here and there. anyway, here's what i've got so far - the 42" oven itself is from BlazingOvens in Canada. Member Matthew helped me out with this crucial component. The castings look really nice. i believe this will turn out to be a great choice for the engine. The trailer is an ex-military unit. The first spark for this project happened when I saw such a trailer on the road one day and thought it would be perfect for this use. it's about the size of a pickup truck bed and is really heavy-duty. That's a good thing since i'll have a considerable amount of weight on it when i'm done. We've built a pan of sorts that bolts into the trailer where the oven will be. it's designed so that it can be removed as a complete unit if we get tired of the trailer deal. We've painted the trailer and lined the bed. The other advantage of this trailer is it's cheap! here are a few pictures of my progress so far. i hope to have it all done in a month. bill

I agree with Matthew fit and finish of the oven look very nice, and mass in CAnada right? not china?the Military Trailer Is perfect for the applications. If I go bigger I was considering the smaller dump trailers beefy and little modification needed. It appears your hearth will be at the right height howevr set ups on grass beaches... Are not allways level will you have jacks for leveling off your trailer? Oh once you start you will see it's quite fun and addictive!

John, i have been looking forward to your input and observations! the floor height is even with the trailer rails - about 46". that's about perfect for me. the trailer has jacks front and back but not side to side. i'm going to try to set the dome this weekend. Matt is right, these castings are really nice. they're made in Canada.

are you talking about rocking on the suspension? it doesn't move around much when i climb around in there so that shouldn't be a problem. what do you mean by top-down pressures? don't like the sound of cave-ins! this oven looks really tight and strong. i do plan to tie it down to the floor pan. i plan to use cables on top of the first layer of insulation. that is mostly for if something bad happens while transporting.

When you go around the corner there are.G forces. Pulling the oven from side to side same thing when you stop I can recommend you create a frame and pour the base of the oven right in place you can also run cable then into this concrete to the oven which also helps secure it. With nothing around the base when you hit a big bump like RR track or somthing its like stomping on top of ball tendancy is to squish. Visual would dropping a waterballoon out PM me and we can go over I don't want to hi jack your thread with my opinionsJohn

John, that sounds like what i've got going. my steel pan is bolted into the trailer, the subfloor is poured into the pan and the dome is secured through the concrete and steel with stainless cables. i'll put up some photos of that later. i'm trying to get the pearlcrete insulating layer done today. please keep the discourse and opinions going, no threat of hijack! thanks,bill

Looking good ! are you going to pour the conc around the insulation and base of dome or am I not seeing it. Cable on my oven were drilled into dome and run back to corners of trailer kinda pulling out a bit. You should be fine! You will be cooking in no time chimney plate and double wall pipe right ? stucco finish? very cool project!! The oven does look very nice! gonna cook like a dream I bet. John

the steel pan has 3" of concrete in it. see #5 and #4 in the top post. i think the cables will hold it all in place, i hope so anyway! chimney is single wall stainless. i'm planning a stucco finish. how do you ensure that your floor doesn't get wet if it rains? i don't think it would be good for the subfloor insulating panels to get wet. i was thinking about a chimney cap and a fitted tarp of some sort. i can park it in a shed but i'm sure it will get rained on at some point.

Looks like a sturdy unit.. both the oven and the trailer! I looked up the oven website, but there isn't a mention of NSF or ETL listings.... seems to be a big deal according to health departments if you want to get licensed. I noticed JConk mentioned it, so I'm going to reiterate that you should really think about double wall chimney.. someone IS going to touch that thing (is this hot??) and it won't be good. I'm not even a crazy safety guy, and I think you should re-think that part.

Why too late? On my earthstone I just used high temp sealant and screwed the mounting plate with Blue concrete screws onto flat surface pipe goes right on plate? easy on and off for transport I posted pics over in flyboy build thread. I envisioned another 2 " layer of concrete around the insulating board before the blanket and perlite Concrete is tapered up over the the actual dome 3-4" up sides, that holds the oven put for sure. . I Think you will be fine your not going racing or off roading (although you are set for Battle with that baby ! Few other thoughts .. do you plan to get it weighed GVWs when complete? did you register it commercial ? Will you be able to move and or spin the unit by hand after disconnecting from truck? or hoping to back into place where it needs to go. That was my quandry with the rear facing or side facing oven. Turns out I can get all most anywhere with 2-3 people pushing and 40" is plenty big ! 3 at a time if good we will see I have 100 people friday night!! back yard beach, drivway any side... again youll be fine. I think they sell more side facing than rear units BTW my mobile oven has only 4 layers of blanket and then stucco so this willl be super duper insulated. !! again great job with the build and more important probaby 1/2 the $$ price !! so 10 less events before profit!John

bill, that is one beautiful portable oven!! do you have any idea of your finished weight? looks like heat retention will be ultra efficient. can you explain the mixture you put over the insulation? is it light in weight ?

JT, i put this on project hold when you were working on your oven. i was ready to buy a FB dome back then and decided to look around. yours seems to have worked out great in the end.

ZaMan, the dome has three layers of ceramic blanket with chicken wire on top to hold it in shape. the next layer is a mixture of pearlite and portland at about an 8:1 mix. it's certainly way lighter than concrete but i still used over 200# of portland. that will be followed by a stucco finish. i'm afraid there's nothing light about this project. i did get a "before" weight on my truck and trailer. i'll know before long the total weight of the trailer and the weight added to the trailer. it may take low range to move it! so far i know this much: the oven shipping weight was around 800#. i probably put that much more into the stand and concrete layer. i'm guessing at least 3-400 more lbs on top of that, not counting firewood, tools, tables and pizza dough.

please keep the discourse and opinions going, no threat of hijack! thanks,bill

Do you have any idea what the weight rating of the trailer is ? My only concern is that since it is a military trailer, that the suspension might be to stiff to provide a good ride for the oven weight.

I can't wait to see it fired. In fact, I emailed them about shipping to the great State of Texas.

Gene,If you're interested in the oven, please let me know I will be more than happy to help you out.
